Howard Feldman Howard Feldman Scope Associates Limited & Director, Satellite IRG ITU Workshop on Satellite Interference, 10 June 2013 Typical Interference Causes  Due to poor equipment or  Due to the User  Transmitting on the wrong Polarization  Transmitting on the wrong Frequency  Transmitting with too high Power level  Transmitting on the wrong Satellite Above, due to poor training or just human error Carrier ID as a solution  Is the best solution when interferer can’t be readily identified  Takes time as it is reactive A Proactive Approach  The MSS operators such as Inmarsat do not have these types of interference Why? Proactive solution MSS systems are typically  Centrally controlled  Closed loop  Individual terminal control  Using only Type Approved equipment Centrally Controlled equipment  Should not be subject to Carrier ID requirements  System doesn’t transmit until satellite is identified  Received commands control the frequency, power level, polarization and timing of the transmissions The Proof  In the MSS world, using centrally controlled approved systems  Many hundreds of thousands of terminals are currently in use  38 years of experience  Accidental Interference issues are extremely rare Howard Feldman Typical Interference Causes Carrier ID as a solution A Proactive Approach Proactive solution Centrally Controlled equipment The Proof
